In many fields, such as banking, healthcare, energy, and climate analysis, where precise predicting of future values is critical for making decisions, time series forecasting plays a critical role. With the quick development of machine learning methods, data-driven approaches have supplemented and frequently surpassed classic statistical models. This work provides a thorough analysis of deep learning architectures, contemporary machine learning algorithms, and traditional statistical models for time series forecasting. Critical analysis is done on important models including ARIMA, Support Vector Regression, Random Forests, Long Short-Term Memory (LSTM), and Transformer-based methods. The study also looks at evaluation criteria and benchmark datasets that are frequently used to compare performance. To illustrate how these models might be used in actual forecasting situations, a case study is provided. Problems including data quality, model interpretability, and computational complexity still exist despite tremendous advancements. Lastly, future directions are considered, such as explainable forecasting systems, automated machine learning, and hybrid models. An organized overview of contemporary developments and difficulties in time series forecasting is offered by this review.
Affective behavior recognition in the wild requires joint prediction of continuous valence-arousal, categorical facial expression, and multi-label action units from unconstrained face images. We present our system for the Multi-Task Learning (MTL) track of the 11th Affective Behavior Analysis in-the-wild (ABAW) competition on s-Aff-Wild2, the static selected-frame version of Aff-Wild2. The method focuses on post-encoder adaptation: frozen AffectNet-supervised backbones provide multi-resolution features, while task-specific temporal heads and cross-task fusion modules select the useful signals for each target. For action-unit recognition, we adapt MAE-Face with Low-Rank Adaptation (LoRA) and use DISFA through per-unit expert routing rather than direct sequential transfer. Ablations over backbone, temporal, fusion, and AU-adaptation choices define the final configuration. The final system obtains P = 1.7302 on the official validation split, showing that post-encoder adaptation and task-wise modeling choices provide a strong MTL pipeline without training a new large-scale face foundation model.
